Coal was a form of fossilized carbon used as a fuel.
The two most common varieties of coal were anthracite, which could be used to fuel non-vented flames such as braziers; and bituminous coal, which needed to be ventilated to burn properly.
Both varieties of coal, in large amounts, were necessary to keep a wizard's laboratory operational. They were available for purchase through Aurora's Whole Realms Catalogue.
Trimia's catalogue of Outer Plane artifacts could manifest lumps of blood-red coal that could transport users to Avernus in the Nine Hells.
